Question

What is the discontinuity of the function f(x) = the quantity of x squared minus 3 x minus 28, all over x plus 4?

Answer 1

For the answer to the question above,
You get discontinuity when in this function you divide by 0. You will divide by 0 if x+4 = 0. That means that x = -4

y value for this example doesn't matter because for x = -4 you will have the discontinuity. Since the only answer that has -4 as x value is D, that has to be the solution.

So the answer is (-4,-11)

Answer 2

Answer:

The discontinuity is (-4,-11)

Step-by-step explanation:

You get the discontinuity when you divide the function by 0. You will divide by 0 if x+4 = 0. That means that x = -4
